  7. b/c w/out the serial number, windows does not know if it is a new device
    that is plugged into the different port or the old one. it treats it as a
    new device. if there is a serial number, windows can track the device from
    port to port.

    But. i had check other device it appears don't support
    serial number in device descriptor(iSerialNumber has a value 0x00).
    It can plug into another port and no need to ask user for the inf file.
    (it does the installation from the inf that already installed in system.)

    Could i do that too? User will complain the inf required again.
    They will kick my ass....

    Is your install package properly signed?

    Dear sirs

    Yes , we had tried to support number for our unsigned driver. it worked.
    but supporting serial number has big problem in mass production. It need
    one more additional operation to burn the serial number on each difference
    device,
    the operation add the cost and customers always not like it.
    They can accept system auto reinstall the driver, but require the inf again.
    The mentioned device :
    also not support serialnumber and it works fine.
    how can it do ?

    By the way..
    we had tried to burn the same serial number on two devices,
    The second device will not be drived when we plug
    the two devices on a system at the same time.



    is it normal?

  13. No, if the device has a serial number, it doesn't matter is the driver is
    signed or not.

  14. yes, this is normal. you are violating the rule that each serial number
    must be unique

  17. It all depends on how your device stores it.

    Dear Doron Holan
    I am trying to get the WHQL signature, before the submition.
    I need to know how to avoid the "ask user for inf file" appears
    every time user plug it to a new port.
    Will the OS compaint disappear after WHQL, no matter what
    the serial number supported or not?
